The Bomag 06550109 O-Ring is a genuine OEM sealing component designed for Bomag pneumatic tyred rollers, including the BW 24 RH, BW 25 RH, BW 27 RH, BW 27 RH-4i, and BW 27 RH-4i BC. Sourced directly from Bomag, this O-Ring matches the original material grade, cross-section, and dimensional tolerances specified for these machines. It fits verified Bomag part number 06550109 applications across the BW-series pneumatic tyred roller lineup. When a seal fails, fluid or air loss follows quickly — replacing it with the correct OEM component restores system integrity without guesswork.
Key Features
- OEM-Grade Sealing Material — manufactured to Bomag's original compound specification, ensuring the correct compression set and resistance to hydraulic fluid, heat, and pressure cycling in pneumatic tyred roller applications.
- Exact Dimensional Match — this O-Ring seats into the original groove geometry without stretching, pinching, or trimming, maintaining a leak-free interface from installation onward.
- Broad Pneumatic Tyred Roller Coverage — confirmed fitment for the BW 24 RH, BW 25 RH, BW 27 RH, BW 27 RH-4i, and BW 27 RH-4i BC pneumatic tyred rollers.
- System Integrity Restored — a correctly seated O-Ring prevents fluid weeping and pressure loss that can compromise steering, braking, or hydraulic function on these rollers.
- Genuine Bomag OEM Part — supplied under part number 06550109 with the assurance of authentic Bomag quality, eliminating compatibility risk during service.
An O-Ring is a looped sealing element that sits in a machined groove between two mating surfaces or around a moving shaft, creating a pressure-tight barrier that prevents fluid or air from escaping a system. On pneumatic tyred rollers like the BW 24 RH and BW 27 RH, O-Rings are used throughout the hydraulic, steering, and braking circuits where maintaining pressure is critical to safe and consistent machine operation. When an O-Ring degrades — through heat cycling, chemical exposure, or mechanical wear — it loses its ability to compress and seal, leading to leaks that can escalate into component damage or unsafe operating conditions if left unaddressed.
